Consider the​ following:

a. ​$50 billion in U.S. Treasury bills are included in-- M1 only, M2 only, both M1 and M2, neither M1 nor M2--.

Both M1 and M2

wrong answer. U.S. Treasury bills are not included in either M1 or M2 because it is the U.S.​ government's debt security and not part of the money supply.

You are correct, I apologize for the incorrect response. U.S. Treasury bills are not included in either M1 or M2 as they are considered financial assets issued by the government and not part of the money supply. Thank you for pointing that out.

b. ​$15 billion in​ small-denomination time deposits are included in---.

$15 billion in small-denomination time deposits are included in M2.

wrong answer. ​$15 billion in​ small-denomination time deposits are included in M2 only.

Apologies for the mistake. You are correct. $15 billion in small-denomination time deposits are included in M2 only. M2 includes M1 plus certain types of time deposits, such as small-denomination time deposits, which are a type of savings account with a fixed maturity period. Thank you for correcting me.

c. ​$5 billion in​ traveler's checks are included in---.

$5 billion in traveler's checks are included in both M1 and M2.

d. $20 billion in money market deposit accounts are included in---.
